Depending on the size, some robot arms can 3D print objects as large as a house — sometimes literally a house. Atropos, the robot arm designed by architects and […]. Through a technology known as Continuous Fibre Composites Smart Manufacturing, Atropos has the potential to create large, complex structures. To print, Atropos uses thermosetting plastic — unlike coming 3D printing operations, which use thermoplastic — with fibres embedded into the print.

Currently, the arm prints with fibreglass, but the team is working on introducing other fibres such as carbon fibre. When the material exits the printer, it is hardened by a UV light, located near the print head. This eliminates the need for temporary supports in many cases. The team was inspired by nature. They mostly studied the behaviour of spiders and silkworms, as well as the fibrous workings of human muscles and tendons, while developing the robot. The aim of the project is to make the production scalable, making anything from very small to very large, complex products for architectural use.

Previous Article Next Article.With STEM subjects finally starting to receive a higher priority within education, there is a greater need than ever for for affordable, user-friendly equipment that helps students learn about technical topics. That technology includes robots, and a new, classroom-friendly, 3D printed robot from French startup Niryo that has taken the internet by storm almost overnight.

Is this the perfect machine for teaching robotics? Kickstarter backers seem to think so. The Niryo One, which launched on Kickstarter over the weekend, is a 6-axis robotic arm made for makers, educators, and small companies.

In addition to the physical arm itself, Lille-based Niryo also plans to build a complete set of cloud services for the Niryo One in order to help out its growing community of users. There are, of course, other robotic arms out there which makers, educators, and small companies can use to learn about robotics.

The reason why many individuals, schools, and businesses never purchase such equipment, however, is usually cost-related. According to Niryo, having six axes allows its new robotic arm to perform tasks that have hitherto been exclusively done by industrial machines.

The arm can pick and place objects with a suction pump, gripper, or electromagnet; it can automate a 3D printer; it can drill holes in objects; it can carry out useful household tasks; it can even—if used creatively—entertain your children. That all sounds very convenient, but the sticking point for most users—especially in the field of education—will be how easy the Niryo One is to use. The Niryo One is even completely open source, so even high-level educators and companies could stretch the limits of the 3D printed robotics arm to suit their own needs.

One feature of the Niryo One that seems particularly geared to group learning projects or even homework! It is still, however, in development, and Niryo will add more features in accordance with user needs and suggestions. Estimated delivery is September Maybe you also like:.

Gantry printers on the other hand typically have cost and stability advantages, offers the ability to make larger prints and even print entire buildings in one go as opposed to the more limited prints of robot printers and the robot printers need for printing single elements. Gantry printers also allow for non-continuous printing, which is needed when printing entire buildings, are far easier to control and does not require highly skilled programmers.

We believe that one of the main drawbacks of robot printers is the limited printable area, which they offer making it particularly difficult to use this type of printer for testing and experimentation. These two critical points, we will try to explain further below:. For robot printers, the following is characteristic: The robot itself is rather large, the arm rather short and the robot needs a lot of clear space around it.

This will severely limit the printable area that each robot printer has. In the following images, this point is illustrated. The robot arm can reach degrees of rotation.

This severely limits the printable area of the robot printers. The above points are illustrated further in the following images. The green is the part of the house that the robot can print, the red part is the part of the house that the robot cannot print. Printable area for the largest robot arm compared to The BOD building. The shortcomings of robot printers in terms of reach when printing from one fixed point become even more clear when it is investigated what a robot printer with an arm with a maximum 3 meter reach which is typically what robot printer companies like Cybe and Xtreee offer can print:.

Printable area for a robot printer with a max 3 meter reach robot arm, typically supplied by robot printer suppliers. It is obvious that such a printer has a very, very limited printable area compared to the gantry printer we sued for The BOD.

One of the ways the robot printer manufacturers try to overcome this problem is to move the robot such that it prints from multiple fixed points or by making the robot mobile.

This, however, also provide a lot of issues as will be explained below. The printer can print the elements off-site or on site. Off-site has the advantage of the printer operating in a more controlled environment but requires transport and assembly of the printed elements on-site.

Such transport cannot be done before the printed elements have hardened enough to be able to handle the transport. This typically first occurs after several days. On-site printing of elements, on the other hand, removes the need for transport, but not the need for assembly and connection of the elements. Also, when printing elements on site the print does not occur in a fully controlled area as would be the case with off-site element printing. On site was the approach Cybe took when printing the laboratory in Dubai.

Smaller elements where printed and then assembled on site, instead of the entire building in one go as was done when The BOD was erected. Thus a user typically cannot just print one layer of a first element the reachable area of the robot from its first fixed positionmove the printer to print the first layer of another element, and then come back and print further on the first element, as the first layer on this element would have set completely once returning to it, whereby layer two would not bind probably to layer 1.

Obviously, to overcome this problem the recipe of the concrete could be adjusted to allow for longer setting time, but even this does not remove the need to assuring that the robot is returning to the first element precisely at the right time, which with several movements of the printer to enable a large print will be very difficult to time. This is likely also the reason why a robot company like CyBe typically chooses to print each element entirely and then connect the elements.

They are just touching each other, but not bonding, making it necessary afterward somehow to connect them.I love to tinker and write about electronics. One aim of this project is to demonstrate that building techniques already found in nature are increasingly becoming possible for us to replicate:. By mimicking the micro-structure of spider silk thread, a specific fabrication strategy has been added into this process. This change makes it possible to print simple self-supporting forms and is capable to show how the form grow from the ground.

In this way, the material develops its full potential to expanded the materiality through the biomimetic printing progress. The programming of the robotic-end effectors is based on Arduino. Each printing head has a heater inside which is uniquely programmed and can precisely maintain the temperature in appropriate range. Also there are tubes sending compressed air to the front of printing head to cool and finalize the material.

Four material ABS deliver system driven by 4 individual servos works like normal 3D printing devices.

Besides, one motor is responsible for the rotating motion of the central turn-plate. Both the speed of delivering and rotating can be changed via the switches on the center stack. Latest David Scheltema. By David Scheltema David Scheltema.

Using a large collection of 3D printed parts, stepper motors, a 3D printer control board, a power supply, and a big pile of off-the-shelf hardware, we will create a large and powerful robot arm.

Did you use this instructable in your classroom? Add a Teacher Note to share how you incorporated it into your lesson. A fairly large collection of parts are required for this build.

Below is the bill of materials for this project. The document has two tabs, the first lists all the parts required to build the 3D printed robot arm, along with sources for parts and approximate prices. Depending on when you order your parts, the prices and availability might be slightly different, but the bill of materials should be mostly accurate.

You can access the bill of materials by clicking the Google Sheets link below. The first tab of the document is the actual bill of materials. This tab lists every part, other than the 3D printed parts, needed to complete this project. I also provided a link to where you can purchase the parts. There are probably any number of sources for the parts, so feel free to shop around. The second tab of the document lists the materials required for each sub-assembly of the robot arm.

This tab is a useful reference as you progress through this build in case you face any confusion about which parts are needed for any particular step.

However, the majority of the parts, especially all of the hardware, is typically available only in packages of much larger quantities than is required for this build. Therefore, the cost is likely to be quite a bit higher than the actual cost of the materials used. The entire structure of the robot arm in this Instructable is made from 3D printed parts. There are quite a few parts involved. Some of the parts are quite large and will take some time to print.

If you don't have access to a 3D printer, or if your 3D printed lacks the build volume for some of the larger pieces, 3D Hubs is a fantastic resource for getting 3D printed parts made quickly and affordably. All of the STL files you will need to print the parts are available in the GitHub repository for this project.

Most parts of the robot arm connect together using heat-set inserts and machine screws. Heat-set inserts are a convenient and fast way to add threads to holes in a 3D printed part. Once pressed into place using a heat source, the brass inserts can be used to fasten together different parts to create strong connections. To install the heat-set inserts, we will need a soldering iron, a pair of hemostats, and a way to hold the 3D printed covers steady.Manufacturing Applications Manager, Tyler Reid, purchased the kit to show the capabilities of our Stratasys 3D printers.

After adding some GoEngineer flare to the arm, he printed out the pieces and I volunteered to assemble it. As I embarked in the assembly of the arm, it became increasingly apparent that the designer of the arm had never assembled it nor considered assembly ramifications while designing the arm.

3D Printing Metal Structures With A 6-axis Robot

In multiple critical pieces such as the shoulder and forearm pieces, the hardware supplied did not fit their designated slots and cavities. For example, in the forearm, a stepper motor is enclosed between two printed parts to provide an axial rotation. The stepper motor shaft was a diameter of 4mm. The goal was to use a coupler to connect the 4mm shaft to an 8mm shaft that would connect to the wrist assembly. The coupler did not fit in the designated slot, and as a result the forearm pieces had to be reprinted.

After the pieces were printed with the correct dimensions, I connected the two shafts and the coupler. After attaching the pieces, I ran into another problem. I disassembled the pieces and used my own die grinder to cut the 4mm stepper motor shaft and the 8mm shaft down so the forearm and write assemblies could fit flush together.

The hardware kit that was supplied was also frustratingly disorganized and incomplete. The instructions for the assembly and wiring of the arm were also painfully lacking. There were fewer instructions included to assemble and use this 3D-printed, 6-axis robotic arm than there are to assemble an IKEA bookshelf.

Regardless, I completed the assembly of the arm and was ready to connect the electrical components. I had to google instructions on how to install Raspbian on a flash drive, interface with the Raspberry Pi, install Python to control the steppers, and get the arm up and going because the instructions were so poor. Fortunately, Dr. One simply uses the controller to move the stepper motors to a set position, create a point, repeat, save, and then run the program.

More complex and sophisticated control logic can be used to control the arm.

But, as far as my responsibilities are concerned, a simple proof-of-concept will suffice for the scope of this project. Now that the arm is assembled and moving, I have graciously relieved my ownership to friend at GoEngineer who specializes in mechatronics and AI programming.

He can add upgrades, improve the control logic, and hopefully use the arm for more useful tasks than bending over and touching the ground.

Nevertheless, the project was a rewarding and gratifying endeavor. I cannot express enough my satisfaction of fighting through all the assembly, wiring, and programming steps and seeing the arm move by manipulating the Xbox controller.

The main challenge is posed by complex geometry; when an object is to be fabricated, the shape must be broken down into a series of machine tool paths that will accumulate material by building up layers in a stable and reliable way. For this reason, 3D printing is generally a very precisely controlled process, both in terms of the type of movement steady acceleration and velocity and the deposition of materials.

In industrial applications, material is deposited or fused in small quantities.

The machines are accordingly operated in a logical, numerical way, just as in CNC machining. Here, the artist is able to express something with the material, often pushing the material to its limits, for example by generating sweeping elegant forms, or revealing new material qualities, such as translucency.

The CFPR has background expertise in ceramics, photo-cure resins and thermoplastics, all of which are being investigated with the new robotic platform. Previous work has evaluated the 3D printer as a tool to manipulate materials, or produce unusual surface textures, as opposed to simply using it as a machine that reproduces digital models at a fine resolution. Using a printer in 'unusual ways' means moving beyond simply using CAD models and slicing algorithms, as these are too automated.

By writing proprietary software, it is possible to develop printing methods from the point of view of how the material can be expressively played with. The robot is running printer paths defined by proprietary software and requires a high degree of automation and real-time responsiveness.

Ceramics can also be deposited so that the material composition is capable of self-glazing in a single firing as opposed to a multiple firing process. These material states may have applications in wider industry. The task of robotically manipulating materials through complex states - for example, sensing and responding to viscosity - requires the integration of several advanced technologies. The MELFA robot allows real-time control and provides a reliable programming interface to allow this to happen.

It also has a large area of reach and movement for a compact robot arm. This makes for an attractive combination of force control, movement range mm reach and reliability, while also being at the right price point. This means that the control program cannot be rigid in its operation. Instead it must constantly and iteratively interpret its working task environment and autonomously correct its behaviour.

What really decided it for us though was the affordability of the robot package and the level of support provided by Mitsubishi Electric. We were invited to the UK HQ to assess a robot and have received excellent technical support throughout the project.
